Magnetic Effect...

A current carrying loop is free to turn in a uniform magnetic field. The loop will then come into equilibrium when its plane is inclined at

A 100 turns coil shown in figure carries a current of 2 amp in a magnetic field 0.2 Wb/m². The torque acting on the coil is

A rectangular coil 20 cm × 20 cm has 100 turns carries a current of 1 A. it is placed in a uniform magnetic field B = 0.5 T with the direction of magnetic field parallel to the plane of the coil. the magnitude of the torque required to hold this coil in this position is

A circular loop of area 0.01 m² carrying a current of 10 A, is held perpendicular to a magnetic field of intensity 0.1 T. The torque acting on the loop is

The magnetic moment of a circular coil carrying current is

What is shape of magnet in moving coil galvanometer to make the radial magnetic field?

Current 'i' is carried in a wire of length L. If the wire is turned into circular coil, the maximum magnitude of torque in a given magnetic field B will be 

In ballistic galvanometer, the frame on which the coil is wound is non-metallic to:

A solenoid of length 0.4 m, having 500 turns and 3A current flows through it. A coil of radius 0.01 m and have 10 turns and carries current of 0.4 A has to placed such that its axis is perpendicular to the axis of solenoid ,then torque on coil will be

In a moving coil galvanometer, deflection of the coil is related to the electrical current i by the relation
